Should share storyboard is paused between all ControlStoryboardAction instances.

if two or more ControlStoryboardAction instances use the same storyboard, is paused will be wrong.

                                Symbol="Refresh">
                        <SymbolIcon.RenderTransform>
                            <RotateTransform />
                        </SymbolIcon.RenderTransform>
                    </SymbolIcon>
                </AppBarButton.Icon>
            </AppBarButton>
        </CommandBar>

When IsBusy is true, the storyboard should be continue to play. But in fact, it don't work for me.

By the way, is this project still alive? The nuget package had 6 months no update.

[mgoertz-msft]

It sure is alive. We listen to you guys when it is time to produce another NuGet update. We have heard request recently and put it on our backlog. Due to higher priority issues though we haven't been able to do so yet.
